Rapid Visco Analyser 4800

The RVA (Rapid Visco Analyser 4800) measures the viscosity and performance of starches, raw materials, ingredients and foods using controlled temperature and shear. It can be used to characterise ingredients, intermediates and finished products to optimise quality and performance.

With an extended temperature range (up to 140°C), the RVA 4800 provides a tool for performing more relevant analyses for a variety of applications, including ingredient (starch and hydrocolloid) performance under conditions relevant to ultra-high-temperature (UHT) pasteurisation of dairy and food products, retorting, pressure cooking, extrusion and other aseptic processing conditions. Temperature and stirring speed (shear) can be programmed to follow international standard methods or use the RVA as a miniature pilot plant to mimic real-world manufacturing and preparation processes such as heating, cooling and mixing.

The RVA 4800 interfaces with a PC and TCW3 software for operation and data management and includes a library of methods for many applications. The RVA 4800 combines speed, precision, flexibility and automation and is a unique tool for research, product development, process monitoring, QC and QA to optimise ingredient use, product formulation and processing conditions.
